Renesas R5F1017DANA#40

Overview

R5F1017DANA#40 from Renesas is a 24-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 48 KB flash, 4 KB data flash, and 2 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (26-channel), and integrated real-time clock for industrial sensor and control applications.

For engineers reviewing the R5F1017DANA#40 datasheet, R5F1017DANA#40 pinout, R5F1017DANA#40 application, or R5F1017DANA#40 equivalent, key selection criteria include its industrial-grade temperature range (−40°C to +85°C), absence of on-chip data flash programming capability, hardware UART/SPI/I²C interfaces, and 24-pin HWQFN (6 × 6 mm, 0.5 mm pitch) package compatibility with space-constrained embedded designs.

Technical Context

The R5F1017DANA#40 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It supports HALT, STOP, and SNOOZE low-power modes and integrates a 12-bit interval timer, real-time clock with calendar/alarm, and watchdog timer with dedicated low-speed oscillator.

Peripheral integration includes up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 8–16 channels of 16-bit timers, 2–4 UART/LIN channels, 2–8 CSI (SPI-compatible) channels, and 3–10 I²C/Simplified I²C channels - all accessible via 24 I/O pins with N-ch open-drain, TTL input, and pull-up options.

FAQ

Does R5F1017DANA#40 support self-programming of data flash memory?

No, R5F1017DANA#40 does not include on-chip data flash programming logic. Unlike R5F1007DANA#40, this variant omits the flash library RAM allocation and self-programming circuitry. Code flash remains writable via on-chip debug interface, but data flash is read-only. Designers requiring field-updatable parameters must select an R5F100x variant instead of R5F101x.

What is the maximum ADC sampling rate achievable with R5F1017DANA#40?

The R5F1017DANA#40 supports a maximum ADC conversion time of 1.2 μs per 10-bit sample under optimal conditions (VDD ≥ 2.7 V, internal clock source). With sequential channel scanning and no wait states, sustained throughput reaches ~500 kSPS across multiple channels. Actual rate depends on clock configuration, resolution setting, and analog input settling time.

Can R5F1017DANA#40 operate reliably at 5.5 V supply?

Yes, R5F1017DANA#40 is fully specified for operation across 1.6 V to 5.5 V. At 5.5 V, all digital I/Os tolerate 6 V on N-ch open-drain pins, and analog peripherals maintain accuracy within datasheet limits. However, power consumption increases linearly with voltage - use lowest viable VDD to maximize battery life in portable applications.

Is the real-time clock in R5F1017DANA#40 battery-backed?

No, the R5F1017DANA#40 RTC does not include a dedicated battery-backup domain. It retains time and date during STOP mode using main VDD supply, drawing only 0.57 μA. For extended power-loss resilience, external supercapacitor or coin-cell backup must be implemented on VDD, as no VBAT pin or dedicated backup regulator is provided.

Which communication interfaces on R5F1017DANA#40 support LIN 2.2 protocol natively?

The UART peripheral in R5F1017DANA#40 supports LIN 2.2 physical layer signaling (SAE J2602) through built-in baud rate generation, sync byte detection, and checksum calculation - no external transceiver or software bit-banging required. Only UART0 (P11/P12) is LIN-capable; UART1 and other serial interfaces lack LIN-specific hardware acceleration.
